Prediction markets have existed in legal limbo since 2003, when U.S. senators killed a Pentagon program that would have let people bet on terrorist attacks. Now the feared scenario has arrived: an Israeli reservist and civilian face prosecution for using classified military intelligence to profit $150,000 on Polymarket, placing bets on the June 2025 Israel-Iran war with suspicious accuracy. It is the first known prosecution anywhere for using military secrets to trade on a prediction market.
The case caps a string of suspicious trades that have plagued Polymarket: a $400,000 windfall from bets placed hours before the U.S. captured Venezuelan leader NicolΓ‘s Maduro, $90,000 in profits from correctly predicting the Nobel Peace Prize winner, and near-perfect calls on Google search rankings. With Polymarket now valued near $10 billion and handling over $12 billion in trades annually, lawmakers are racing to decide whether prediction markets are valuable price-discovery tools or national security liabilities that incentivize insiders to monetize secrets.
